Yes.

It means emacsclient is waiting for the server to indicate that
editing of the file is done.  This is for programs which invoke an
editor, let the user edit some text, then continue processing that
text after the user finishes editing it.

The --no-wait option is exactly what you want.  If you can explain
what was unclear about it in the help text, perhaps we could clarify
that.

Thanks.
